This is typical with dual boot systems. I've seen it many times on systems dual-booting the nasty and Linux. One OS sees the hardware clock as local time and the other references it as GMT time and adjusts the time based on your timezone.

I believe there is a setting in the nasty that will allow you to have it see the hardware clock as GMT (toggling that on or off should fix the issue). I'm on my iBook right now so I can't verify._________________ -=iMav=- http://geekhack.org
